Description

Technical Field

[0001] The present invention relates to the field of building construction, and more particularly, to a reinforcing device for an arc formwork. Background Art

[0002] In the construction field, curved formwork is mainly used to form arc or curve structures during concrete pouring. Traditional curved formwork is reinforced with scaffolding pipes, tie rods, etc., and in some positions, the way of setting the top of the scaffolding pipe is used for reinforcement. There are situations such as long construction time and uneven reinforcement of each part. If the curved formwork is not firmly reinforced, it will cause problems such as formwork explosion and deformation during concrete pouring. Sometimes, there is a slope between the upper and lower parts of the curved formwork, resulting in inconsistent diameters of each part and greater reinforcement difficulty. Summary of the Invention

[0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a reinforcing device for an arc formwork, which can complete the reinforcement of the arc formwork better, faster and more conveniently, and ensure the quality of the formed concrete.

[0007] Further, the upper end of the bottom plate is welded to the lower end of the connecting sleeve, the wire rope connecting part is welded to the bottom plate, and the connection part between the wire rope connecting part and the wire rope is located outside the lead screw.

[0008] Further, an operation groove is provided in the middle of the lead screw, and an operation hole is provided in the middle of the operation groove.

[0009] Further, the external threads at both ends of the lead screw have opposite helix directions.

[0010] Further, the connecting sleeve is a hexagonal nut.

[0011] Further, the wire rope connecting part is a hook.

[0012] Further, the wire rope connecting part is arc-shaped.

[0013] Further, the wire rope connecting part includes two longitudinal rods and a cross bar, the cross bar connects the two longitudinal rods, and one end of the wire rope is connected to the cross bar.

[0014] Advantageous Effects

[0015] The present invention can set multiple fastening devices according to the height and size of the arc template. During use, only a joystick is needed to rotate the lead screw, so that the lead screw rotates, pulls the bottom plate to move, the bottom plate drives the wire rope connecting part to move, the wire rope connecting part drives the wire rope to be tightened, and the wire tightens the arc plate, completing the reinforcement of the arc template better, faster and more conveniently, and ensuring the quality of the concrete pouring molding.

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] As shown in the figure, the present invention discloses an arc template reinforcement device, including a lead screw 1, a connecting sleeve 2, a wire rope connecting part 3 and a wire rope 4. External threads are provided at both ends of the lead screw 1, internal threads are provided in the connecting sleeve 2, the connecting sleeve 2 is installed at both ends of the lead screw 1, bottom plates 5 are respectively installed at the bottoms of the connecting sleeves 2, the wire rope 4 is installed on the bottom plates 5, and the wire rope 4 is sleeved outside the arc template 6. By rotating the lead screw 1, the lead screw 1 is connected by threads to drive the wire rope connecting part 3 to move horizontally, and the bottom plate 5 plays a limiting role to prevent the wire rope and the wire rope connecting part 3 from rotating, and to prevent the wire rope 4 from rotating in the reverse direction and loosening after stopping. The bottom plate 5 enables the wire rope connecting part 3 to only move horizontally and not rotate.

[0021] In an embodiment of the present invention, both of the two bottom plates 5 are attached to the arc template 6. The arc template 6 also plays a role in limiting the bottom plate 5, so that the bottom plate 5 can only slide on the arc template 6.

[0022] In an embodiment of the present invention, the upper end of the bottom plate 5 is welded to the lower end of the connecting sleeve 2, the wire rope connecting part 3 is welded to the bottom plate 5, and the connection part of the wire rope connecting part 3 and the wire rope 4 is located outside the lead screw 1. In this way, the rotation of the lead screw 1 will not affect the wire rope connecting part 3.

[0023] In an embodiment of the present invention, an operation groove 11 is provided at the middle of the lead screw 1, and an operation hole 12 is provided at the middle of the operation groove 11. The setting of the operation hole allows the operating rod to pass through, and by manually rotating the operating rod, the lead screw 1 can be driven to rotate. The operation groove 11 facilitates inserting the operating rod into the operation hole 12.

[0024] In an embodiment of the present invention, the external thread directions at both ends of the lead screw 1 are opposite.

[0025] In an embodiment of the present invention, the connecting sleeve 2 is a hexagonal nut. The hexagonal nut is convenient to find at the construction site and convenient for processing the reinforcement device.

[0026] In an embodiment of the present invention, the wire rope connecting part 3 is a hook.

[0027] In an embodiment of the present invention, the wire rope connecting part 3 is arc-shaped.

[0028] In an embodiment of the present invention, the wire rope connecting part 3 includes two longitudinal rods 31 and a cross bar 32. The cross bar 32 connects the two longitudinal rods 31, and one end of the wire rope 4 is connected to the cross bar 32.

[0029] Each arc-shaped template 6 is provided with multiple groups of reinforcement devices. Both ends of each wire rope are respectively connected to the wire rope connecting parts. Each group of reinforcement devices includes two lead screws 1, four connecting sleeves 2, four wire rope connecting parts 3, and two wire ropes.
